Right now, if m_contentType is already set but contentType is not, then the header will be set. This is good. If m_contentType is set and contentType is also set, then m_contentType will be set. This is also good. But then the header will be set back to its original value. This is a wasteful operation. I guess there's not a string copy, though. Just setting a value in a HashMap<enum, String>, so it might not be worth the check.

Shouldn't this be if > (!m_contentType.isNull() && contentType.isNull()) ? We are sometimes doing a get then a set, if there is no content-type header. We could optimize this by using a single HashMap::add call. Not sure whether that situation happens often enough on HTTPHeaders to add such code?
